(54) Power regulation feedback to optimize robustness of wireless transmissions


(57) A wireless communication system with power regulation feedback for improving the robustness of wireless communication transmissions between a receiver and an active emitter irrespective of the distance separation therebetween. The receiver receives wireless communications and detects a voltage induced therein. A feedback loop provides wireless transmission of power regulation feedback based on the detected voltage. The active emitter generates a power regulated data signal in which at least one of maximum and minimum bit voltage levels of respective logical high and low bits is adjusted based on the induced voltage received via the feedback loop. The RF power level, modulation index, and/or slew rate of a data signal emitted from the active emitter is regulated by adjusting at least one of maximum and minimum bit voltage levels of respective logical high and low bits based on voltage induced in the receiver during a previous communication from the active emitter.
